In reply to Clive. timeClient.update() need not be called every time the application needs time. As you suggested, every hour or so (I'm guessing) should be sufficient to correct the internal clock. When I use my pfSense router as the NTP server, it ignores requests more frequent that 1/minute.

Hello Sara

I am following your examples and am receiving epoch time. Is there a way to get epoch time out to milliseconds? I am loading data into a firebase database and using an android app to display. The android time stamp/epoch time is out to milliseconds (13 characters).

In reply to Richie. Your Board version was likely around 2.4.2. If you upgrade to 2.5.0, you will pass that problem, but still likely to have Wifi issues. So, you have to upgrade to 2.5.2 or newer.

Hi
How check latest update from server ?, if internet Connection is lost.
will try, to check
Serial.print(timeClient.forceUpdate());
Serial.print(timeClient.update());
but every time >> timeClient.update() is 0

when it connect with internet >> timeClient.forceUpdate() is 1 and if loss connection its print 0

any other way to chack latest update from server ?

after lost internet connection time will be continues updated, not understand why ?
Serial.println(timeClient.getFormattedTime());

I solved the incorrect year problem by introducing a new library.

#include // Time Library
unsigned long epochTime = timeClient.getEpochTime();
int currentYear = year(epochTime);

In this way, no more false information will appear.

In reply to Geert. Take a look at this library. Is calculate according to the date you give with getCurrentDate. github.com/buelowp/sunset

In reply to indrajit.

The 1970 is when it cannot get time from the internet and will use the start of epoch time.
Add an if statement checking the year. If it’s 1970, try to get time again.

Sara
